Numerical solution of elliptic distributed optimal control problems with boundary value tracking
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We consider some boundary value tracking optimal control problem constrained by a Neumann boundary value problem for some elliptic partial differential equation where the control a…
Paving the way to a -coercive method for the wave equation
Daniel Hoonhout, Richard Löscher, Carolina Urzúa-Torres
In this paper, we take a first step toward introducing a space-time transformation operator that establishes -coercivity for the weak variation…
A unified framework for the analysis, numerical approximation and model reduction of linear operator equations, Part I: Well-posedness in space and time
Moritz Feuerle, Richard Löscher, Olaf Steinbach +1
We present a unified framework to construct well-posed formulations for large classes of linear operator equations including elliptic, parabolic and hyperbolic partial differential…
State-based approach to the numerical solution of Dirichlet boundary optimal control problems for the Laplace equation
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We investigate the Dirichlet boundary control of the Laplace equation, considering the control in , which is the natural space for Dirichlet data when the stat…
State-based nested iteration solution of optimal control problems with PDE constraints
Ulrich Langer, Richard Löscher, Olaf Steinbach +1
We consider an abstract framework for the numerical solution of optimal control problems (OCPs) subject to partial differential equations (PDEs). Examples include not only the dist…
Efficient Solution of State-Constrained Distributed Parabolic Optimal Control Problems
Richard Löscher, Michael Reichelt, Olaf Steinbach
We consider a space-time finite element method for the numerical solution of a distributed tracking-type optimal control problem subject to the heat equation with state constraints…
